Frequently asked questions
- What size room counts as large for an air purifier?
- There is no fixed cut-off, but large-room models typically target open-plan living spaces and sizeable rooms. Match the stated room rating, or size up, so the unit clears the air at a sensible setting.
- Will a large purifier be noisy on full power?
- Higher airflow usually means more noise at top speed. Many models run quietly on low or auto modes, so check decibel figures if it will sit in a living room or bedroom.
- Are running costs higher for large-room models?
- Bigger units can use more electricity and have larger filters that cost more to replace. Running on auto mode and changing filters on schedule helps keep ongoing costs predictable.
